Not of help in the present situation, but. The current lock-down aside, have you ever come across an unemployed plumber or electrician? Yes,I know, it takes an apprenticeship, at least in UK. Apart from events like this, the job is very dependent on things like medicals. I had to retire medically just before turning 58. Luckily the pension kicked in at 60, but that two years was a case of living on savings, and being unable to find a job anywhere. Advice to a young man: train as a plumber/electrician/welder/ heavy-goods driver. Then go fly.
